Merge #1074 
1074: Implement ETC2 and ASTC textures r=kvark a=cwfitzgerald

**Connections**

Closes #1070. Makes progress towards #1069.

**Description**

This PR has multiple functions:
 - Adds ETC and ASTC compressed textures behind features.
 - Adds three helper functions on `Extent3d` that help in calculating mip sizes: `at_mip_level`, `max_mips`, and `physical_size`.
 - Refactors various conversions into a public `TextureFormat::describe` function. I have used a decl macro to ease in the declaration and modifcation of an otherwise horribly verbose function.

I have tried to use clever multi-select based data copying to reduce the possibility for errors, but there's a _lot_ of data moving around here.

**Testing**

Upcoming wgpu-rs pr adding wider compressed texture support to the skybox example. Helper functions were tested with doctests.

Marked as draft until I can get the wgpu-rs pr done and prove it works, it is, however, ready for review.

README.md

This is an active GitHub mirror of the WebGPU implementation in Rust, which now lives in "gfx/wgpu" of Mozilla-central. Issues and pull requests are accepted, but some bidirectional synchronization may be involved.

WebGPU

Matrix Matrix Build Status

This is the core logic of an experimental WebGPU implementation. It's written in Rust and is based on gfx-hal with help of gpu-alloc and gpu-descriptor. See the upstream WebGPU specification (work in progress).

The implementation consists of the following parts:

  • Crates.io docs.rs - internal Rust API for WebGPU implementations to use
  • Crates.io docs.rs - Rust types shared between wgpu-core, wgpu-native, and wgpu-rs
  • player - standalone application for replaying the API traces, uses winit

This repository contains the core of wgpu, and is not usable directly by applications. If you are looking for the user-facing Rust API, you need wgpu-rs. If you are looking for the native implementation or bindings to the API in other languages, you need wgpu-native.
